title: Radiopacity with vertical indentations.
abstract: An elliptical radiopacity with vertical indentations at its border was seen in the radiograph of an edentulous patient. Interpretation of the image was based on a correlation of the clinical findings with a review of the image projection that occurs during exposure of a maxillary posterior periapical radiograph.
